Carbon forms the hardest known solids and offers the opportunity for new materials with outstanding properties. The aim of this project is to establish a new technology for synthesising dense, diamond-like carbon materials without the need for high temperatures. The approach uses shear stress caused by non-hydrostatic compressions to drive phase changes in solids. Guided by modelling and using novel experimental techniques, this project seeks to understand and then exploit this remarkable phase change phenomenon. Expected outcomes include hard and tough coatings for high performance tools, impermeable encapsulations to enhance the longevity of bionic implants and a possible explanation for the mystery of deep earthquakes.

碳构成最难的已知固体，并为具有出色特性的新材料提供了机会。该项目的目的是建立一种新技术，用于合成浓密的，类似钻石的碳材料，而无需高温。该方法使用由非静态压缩引起的剪切应力来驱动固体的相变。通过建模和使用新型实验技术的指导，该项目试图理解并利用这种非凡的相变现象。预期的结果包括用于高性能工具的硬和坚硬的涂料，不可渗透的封装，以提高仿生植入物的寿命以及对深层地震奥秘的可能解释。
